I am trying to trace what employment he did in the period 1933/1941 my birth certificate states he was a sound engineer for Rank which was British Acoustic Films from 1941 was there a cinema in Mitcheldean in the period 1933/41 where he infact possibly could have been reposible for the Sound

The dates for EDGS seem a little wrong - was he there from age 5 - 11 ?

Assume you were born post 1941, my guess is he worked at BAF rather than a local cinema, BAF was in the film / cinema equipment business as well as various "war effort" projects....
